The Times Labs blog takes a hard look at the data on music sales and live performances and concludes that while the labels' profits might be falling, artists are taking in more money, thanks to the booming growth of live shows. The Times says that they'd like more granular data about who's making all the money from concerts — is there a category of act that's a real winner here? — but the trend seems clear. The 21st century music scene is the best world ever for some musicians and music-industry businesses, and the worst for others. Which raises the question: is it really copyright law's job to make sure that last years winners keep on winning? Or is it enough to ensure that there will always be winners?
